NOTE • Be sure to check jack type, signal level, timing and resolution

before connecting this projector to a PC.

• Some PCs may have multiple display screen modes. Use of some of these

modes will not be possible with this projector.

• Depending on the input signal, full-size display may not be possible in some

cases. Refer to the number of display pixels above.

• Although the projector can display signals with resolution up to UXGA

(1600x1200), the signal will be converted to the projector’s panel resolution

before being displayed. The best display performance will be achieved if the

resolutions of the input signal and projector panel are identical.

• Automatic adjustment may not function correctly with some input signals.

• The image may not be displayed correctly when the input sync signal is a

composite sync or a sync on G.

・HDMI input does not support the signals marked with *.
